BALINGr-PRESS.

Application led August 14, 1915.

To all whom t may concern Be it known that l, Jnssn M. BONDURANT,V

a citizen of the United States, residing at Figsboro, in the county of Henry and State of Virginia, have invented certain new and useful Improvements in Ealing-Presses, of which the following is a specification.

rlfhis invention relates to baling presses for hay or similar materials and the principal object thereof is to provide attachments to such machines whereby they will be rendered suitable for use directly with power threshing machines or the like.

Heretofore it has been impractical to drive balers of the reciprocating plunger type direct from threshing machines because of the tendency of the baler to race on the return stroke of the plunger.

Among the objects of this invention is to provide means to prevent this racing and at the same time and in connection therewith to provide a feeder whereby the straw from the drag of the thresher may be fed directly into the baler.

With these general and specific objects in view the invention consists in the formation, combination and arrangement of the various elements as will be herein described and claimed.

In the drawings, Figure 1 is a side elevational view, partly in section, of a baler embodying the features of my invention, several of the parts thereof being removed for the purpose of clearness in the drawing; Fig. 2 is a partial plan view of the same with the feeding mechanism removed; F ig.

3 is a part side elevational view showing the essential features which were omitted in Fig. 1; Fig. 4 is a transverse vertical section taken on the line A B, Fig. 3, this gure being drawn to an enlarged scale over that of Fig. 3; Fig. 5 is a side elevational view of the brake lever as used in the mechanism, certain related parts being indicated in their positions relative to the said lever; and Fig. 6 is an end elevational view of the said lever.

Referring to these drawings, 1 represents the frame work of a well-known type of baling press and 2 the ground wheels thereof.

At 52 is a customary head block and at 53 are the non-return ngers whereby the compressed material is prevented from following the ram on the return stroke.

At 3 is the reciprocating plunger or ram Specification of Letters Patent.

which is operated by means of the connecting rod 4. 'The connecting rod 4 is actuated by means of a crank 5 on a shaft 6, the said shaft being journaled in suitable bearings 7. Secured to the shaft 6 are duplicate4 gear wheels 8 which mesh with and are driven by the gear pinions 9, these pinions being afiiXed to a jack shaft 10. Bearings 11 are provided for the shaft 10. Secured to the jack shaft 10 is a gear wheel 12 which meshes with and is driven by a pinion 18 on a drive shaft 14, this shaft 14 carrying also the main belt pulley 15 for driving thebaler, and being journaled in the bearings 16. Thus the belt 17 will, through the train of gearing just described, give reciprocating movement to the ram 3. And it will be realized that as the compression of the material to be baled takes place only on the advance of the ram the return thereof unloaded will tend to make the machine pulsate or race, and such irregularity will be felt back to the main driving unit. It is this pulsating that is undesirable in threshing machines and it has heretofore pre eluded the driving of a baler from the same drive unit with a thresher, unless the driving unit is of a sufficiently large capacity as to not be subject to noticeable variations in speed due to this change in load.

The baling mechanism just described is given as a typical construction although it is to be understood that the features of my device may be employed with many diHerent forms of baler.

My invention consists in general of a brake adapted to be alternately applied and released to some moving part of the baler drive together with means acting in timed relation with the movements of the ram to effect such brake action. To perform this I provide a shaft 18 which is journaled in bearings 19 and which carries the gear wheel 20. rlhe gear 2O is actuated by a comeshing gear 21 on a shaft 22, this gear 21 meshing also with and being driven by a gear wheel 9.3 on the crank shaft 6. These gearsare so proportioned that the shaft 18 rotates at the same speed as the crank shaft, or in other words, so that it will make one revolution for each cycle of the ram. A fXed to the outer end of the shaft 18 is a cam 24 and this cam provides actuating means for a lever 25, said lever being fulcrumed to the frame of the baler at 26 and the cam engaging the opposite or outer end of the said lever. As the baler operates, it will be seen that the lever 25 will be depressed once for each cycle of the ram,vand the cam is so formed and so positioned on the shaft 18 that the lever will be depressed gradually during the advance of the ram and will then suddenly return to the position shown in the drawings, or the applied brake position, when the ram has'reached the limit of the advance stroke. During the return stroke thev lever remains in the applied position and the actuation of the'lever begins only when the ram starts to advance. During the return stroke of the ram the end of the' lever rides on the concentric portion 27 of the cam 24 and the cycloidal portion 28 of the camgradually depresses the'lever during the advance stroke, thus gradually decreasing the braking effect' as the compression of baling increases, until when the end of the stroke is reached the brake for an instant is practically released. The lever` then drops over the shoulder 29 on the cam a'nd the full braking power is instantly applied and continues for the full return stroke of the ram. Y

The brake proper is preferably of the bandtype, the band wheel or friction wheel 30 being secured to the end of the shaft 22.V The band 31 is aixed to a bracket 32 which issecured to the frame 1 and extends outwardly over the lever. Extending downward through the bracket 32 and restrained thereby is a bolt 33, the same being threaded at its lower end at 34. The lever 25-is made with a vertical socket 35 through the same with a bracket or wall 36 extending above this socket. This wall is pierced to.

admit the bolt 33, which extends through the socket. The socket serves to receive and retain a coil spring 37. rIhis spring surrounds the bolt 33 and at the lower end thereof lits into a cup-shaped washer 38 through which the bolt 33 passes. Immediately beneath the cup-shaped washer 38 is a hand nut 39 on the-bolt 33 by means of which the` tension of thespring 37 maybe regulated. The band 31 passes from the fixed bracket 32 around the brake wheel 30 and thence to the socket of the lever 25 where the free end ofthe band is positioned between the under side of the wall 36 and theV top of the sprino 37, the bolt 33 passing llooosly through a iole in the end .of this I t lwillbe seen that with the lever in the position as shownin Figs. 3 and 5 the band will be held forcibly against the-circumference of the bandwheel by the action of the spring 37 between the washer 38 and the free end of the band.V And likewise the action ofl this spring will forcethe end of the lever l25 at all times against the cam 24. V When theaction of the cam depresses the leverv the free 4end ofthe band will be forced downward, releasing the same from its contact with the brake wheel and compressing the spring 37 between the free end of the band and the cup washer 38, thus releasing the brake as desired. Thus it will be seen that I have provided an efficient and correctly-timed brake and having so provided I am now enabled to use in connection.

therewith on baling presses a feeding attachment whereby the straw will be fed directly from the thresher into the baler.

My self-feeder is shown only in Fig. 1, its form and operation being clearly disclosed in this ligure. The entire feeder is mounted over the hopper of the baler and consists of an inclined receiving leg 40 and a vertical delivery leg 41. The receiving leg is made to admit the outer end of the drag 42 of the thresher and is supplied with a suitable drag 43 extending across the bottom of this leg and traversing the same longitudinally thereof. Along the top of this receiving leg are a series of longitudinallydisposed rakes 44, the same being swung at one end on links 45 and being `iournaled at their other ends on a crank 46. When the crank shaft and crank 46 are rotated by means of the belt 47 and pulley 48 it will be seen that the rakes will be given a reciprocating-vibratory movement and the straw from the drag 42 will be propelled down this leg between the drag 43 and the rakes 44 and it is delivered into the vertical leg 41. This leg `41 is supplied with a similar series of rakes 49 which have motion identical with that just described for the rakes 44, but no drag is used with this vertical leg as the weight of the straw will tend to carry it downward into the hop per of the baler. The rakes 49 are hung on links 50 and are actuated by the crank 51. The stiles of both the rakes 44 and 49 are disposed without the respective legs and the teeth thereof extend through suitable slots in the casing of the legs. Thus I have provided a self-feeder which when used in connection with my braking device may be used with and driven directly from an ordinary threshing machine.
